Three friends owe 18 dollars to another friend for gas if they plan to split the cost evenly which of the following expressions could they use to find how much they each owe
If they plan to split the cost evenly, the expression that could be used to find how much they each owe is 18/3
How to determine the amount paid by each?The given parameters are:
Total amount owed = 18 dollars
Number of friend = 3
If they plan to split the cost evenly, the expression that could be used to find how much they each owe is represented as:
Amount = Total/Friends
This gives
Amount = 18/3

a jet bomber traveling 500 mph arrived over its Target at the same time as its fighter jet escorted which left the same fate 2.5 hours after the bomb took off how many hours did the bomber take to reach the target of the fighter jet travel at 60 miles per hour
Since the jet bomber arrived over its Target at the same time as its fighter jet escorted, it took the jet bomber 0.34 h to reach the target.
To find the number of hours, we need to solve simultaneous equations.
What are simultaneous equations?Simultaneous equations are pair of equations which contain two unknowns.
How to calculate the number of hours the bomber jet took off?Let
D = distance travelled by both bomber jet and fighter jet.t = time bomber jet took off v = speed of bomber jet. T = time fighter jet took off and V = speed of fighter jet.So, D = vt
D = 500t (1)
Also, D = VT
D = 60T (2)
Since jet bomber traveling 500 mph arrived over its Target at the same time as its fighter jet escorted which left the same fate 2.5 hours after the bomb took off.
T = t + 2.5
So, D = 60(t + 2.5) (3)
The required simultaneous equationsD = 500t (1)
D = 60(t + 2.5) (3)
Equating equations (1) and (3), we have
500t = 60(t + 2.5)
500t = 60t + 150
500t - 60t = 150
440t = 150
t = 150/440
t = 15/44
t = 0.34 h
So, it took the jet bomber 0.34 hours to reach the target.

Answer:
Step-by-step explanation:96 in the fourth since they are adding the answer itself two times before you get the other like 12 bacteria and then 24 so that means 12 + 12 is 24 and the third one 48 so 24 +24 =48
fourth 48 + 48=96
fifth 96+96=192
sixth 192+192=384

There are 26 prize tickets in a bowl, labeled A to Z. What is the probability that a prize ticket with a vowel will be chosen, not replaced, and then another prize ticket with a vowel will be chosen? Does this represent an independent or dependent event? Explain.
Using it's concept, there is a 0.0308 = 3.08% probability that a prize ticket with a vowel will be chosen, not replaced, and then another prize ticket with a vowel will be chosen. Since the letter is not replaced, the number of outcomes change, hence they are dependent.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For the first ticket, since 5 out of 26 letters are vogal, the probability is:
5/26.
For the second ticket, since there is no replacement, the probability is:
4/25.
The probability of both tickets is:
[tex]p = \frac{5}{26} \times \frac{4}{25} = 0.0308[/tex]
0.0308 = 3.08% probability that a prize ticket with a vowel will be chosen, not replaced, and then another prize ticket with a vowel will be chosen. Since the letter is not replaced, the number of outcomes change, hence they are dependent.

Answer:
-70
Step-by-step explanation:
We are given this arithmetic sequence:
-2, -6, -10, -14, ...
And we want to find the 18th term in it.
The 18th term can be found using this formula:
1st term + common difference(desired term-1)
The desired term is the term that we are looking for. In this case, it would be the 18th term, so substitute 'desired term' with 18.
1st term + common difference(18-1)
So, let's find the first term and the common difference.
The 1st term is the first term (number) that appears in the sequence. In this case, that number would be -2.
The common difference can be found by doing second term minus first term.
Remember that we know that the first term is -2. The second term is the second number that appears in the sequence, which would be -6.
So, do -6 subtract -2.
-6 - - 2
-6 + 2
-4
The common difference is -4.
So, we can plug -2 and -4 into the formula.
-2 - 4(18-1)
Now, doing the order of operations, first, subtract 1 from 18.
-2-4(17)
Now multiply -4 and 17 together.
-2 -68
Subtract -68 from -2.
-70
The 18th term of the sequence is -70.
Find the area of the convex polygon with vertices (0,5), (-1,2), (4,4), (-3,-4) and (2,0).
The area of the convex polygon is 21.5 square units
How to determine the area of the convex polygon?The vertices are given as:
(0,5), (-1,2), (4,4), (-3,-4) and (2,0)
The area is then calculated as:
A = 0.5 * |x1y2 - x2y1 +x2y3 - x3y2 + ....... |
So, we have:
A = 0.5 * |-1 * 5 - 2 * 0 + 0 * 4 - 5 * 4 + 4 * 0 - 4 * 2 +2 * -4 - 0 * -3 - 3 * 2 + 4 * 1|
Evaluate
A = 0.5 * |-43|
Remove the absolute bracket
A = 0.5 * 43
This gives
A = 21.5
Hence, the area of the convex polygon is 21.5 square units

Step-by-step explanation:
a parallel line has the same slope but different y intercept
so we need to solve for y=-2/3x+b
since it passes through 4,-5 we can plug it in for x and y

-5=(-8/3)+b then add 8/3 to both sides

It took an hour to now a lawn using a mower with 14 inches blade. How long will it take using a mower with 12 inches wide
If the time taken by 14 inches wide is one hour then the blade of 12 inches wide will take 1 hour 17 minutes to mow a lawn.
What is width?
The width of something is the measurement of one side of a body. It is generally less than length of that body or shape.
How to calculate time?
We have been given time of 1 hour if blade is 14 inches wide and we have to calculate time taken by 12 inches wide blade:
It will be as 14/12* 1 hour
=14/12
=1.167
=1.17 hour
Hence the time taken by the blade of 12 inches wide will be 1 hour and 17 minutes.
Answer:
70 mins
Step-by-step explanation:
This is called inverse proportion.
1hr : 14in
x hr : 12in
Ask yourself, what do you do to 14 to get 12? To find this out, we do:
14 / 12 = 1.16666667
Since the blade is smaller, it will take longer. So, we times 1hr by 1.16666667 to get
1.16666667 hrs =
1.17 hours (rounded)
This is 70.2 mins, or 1hr 10 mins

The probability of winning 15 out of the 22 games is [tex]P = 0.099[/tex]
what is the probability of winning more than 15 times?We know that the probability of winning on the arcade game is 0.568.
Then the probability of losing is:
P = 1 - 0.568 = 0.432
The probability of winning 15 out of 22 games is given by the equation:
[tex]P = C(22, 15)*(0.568)^{15}*(0.432)^{7}[/tex]
Where C(22, 15) is the number of combinations of 15 elements that we can make with a set of 22 elements, given by:
[tex]C(22, 15) = \frac{22!}{(22 - 15)!*15!} = \frac{22!}{7!*15!} = \frac{22*21*20*19*18*17*16}{7*6*5*4*3*2*1} = 170,544[/tex]

John noticed that the angle formed by the minute hand and hour hand on a standard 12-hour clock was 110 degrees when he left home after 6 p.m.; it was also 110 degrees when he returned before 7 p.m. that same night. If he left home for more than five minutes, for how many minutes was he away
Jhon was between 6:12 p.m and 6:52 p.m. So, Jhon left home for exact 40 minutes. Using the angle made by the hands in the clock, the required value is calculated.
How to find the angle between the minute hand and hour hand?The general formula for finding the angle between the minute hand and the hour hand is
M = [tex]\frac{2}{11}[/tex] (H × 30 ± θ)
Calculation:It is given that,
Jhon left home after 6 p.m with an angle of 110° formed by the minute hand and hour hand.
So,
M = [tex]\frac{2}{11}[/tex] (H × 30 - θ)
= [tex]\frac{2}{11}[/tex] (6 × 30 - 110)
= [tex]\frac{2}{11}[/tex] (180 - 110)
= [tex]\frac{2}{11}[/tex] × 70
= 140/11
So, he left after 6:12 p.m
Jhon returned home before 7 p.m with angle of 110° formed by the minute hand and hour hand.
M = [tex]\frac{2}{11}[/tex] (H × 30 + θ)
= [tex]\frac{2}{11}[/tex] (6 × 30 + 110)
= [tex]\frac{2}{11}[/tex] (180 + 110)
= [tex]\frac{2}{11}[/tex] × 290
= 580/11
So, he returned before 6:52 p.m
Then,
The time taken for returning home = 580/11 - 140/11 = 440/11 = 40 minutes.
Therefore, he took 40 minutes to return home.

Assuming they follow the same population
growth rate, it is predicted they will have 6.65

the population of province is growing at the rate of 2.91%
What is the formula of the rate of growth of a population?the formula of the rate of growth of a population =
[(future population- initial population/initial population)*100]/time
population in 2016 = 4.2 milllion = 4200000
Population predicted in 20 years = 6.65 million = 6650000
so, initial population = 4200000
future population = 6650000
rate of growth = {(6650000- 4200000/4200000)*100]/20
= 58.33/20
